Official: Islamic State leader in Libya likely killed in US airstrike

A senior U.S. official says an American airstrike has targeted and likely killed a top Islamic State leader in Libya.

The official says the airstrike struck a command and control center near the eastern port city of Darnah and likely killed Abu Nabil and others with him. Officials are still assessing the results of the strike but called Nabil's death strongly probable.

The official says the strike by an F-15 fighter jet took place shortly after the Paris terrorist attacks were underway, but had been planned for some time. The aircraft were in the air when the attacks began in France.

The official was not authorized to discuss the strike publicly so spoke anonymously.
